To all 'whom it may concern.:

Be 1t known that I, SAMUEL GAnviN, a citizeii of the United States, residing at Custer,

m the county of Yellowstone and State of Montana, have invented certain new and useful Improvements in Endless vWater-Conveyers, of which the following is a s eci'lication.

This invention 'relates genera y speaking to endless bucket conveyers for general use and especially to a conveyer of this type designed for the elevation of water for irrigatiiig and other purposes.

The invention consists of certain specific details of construction which will be hereinafter fully described and illustrated on the accompanying drawinvs in which,

Figure 1 is a side e evation of the invention, shown in operative position; Fig. 2 is a 3 is a diagram of the blank from which the bucket is made; Fig. .4 is an end view of a bucket; Fig. 5 isa detail of one of the chain links, and Fig. 6 is a detail of a valve in the bottom of the bucket.

Throughout the following description and on the several views of the drawings similar parts are referred to by like reference charac. ters.

In the preferred embodiment of the invention the saine includes a tower l0 of any suitable construct-ion and dimensions. As indicated the tower 10 comprises substantially vertical u )rights 11 and 12, tlie u rights bcing suitably connected and braced) by a bottom member 13 and a top frame member 14. The tower 10 is adapted to be supported upon any sort of a support, such as a trolley, boat, or the like, such supporting device not being illustrated inasmuchas the saine con` stitutcs ne portion of the present invention. For convenience of description the uprights fragmentary rear elevation of the saine; Fig.

' 11 will' be considered as defining the front of the machine, and the uprights 32, the rear of the machine. A

Journaled transversely of the .tower at or near the lower rear corner is a shaft 15 carryiniT near each end an idler sprocket wheel 16.

Likewise at the upper and rear corner of the tower 10 is a shaft 17 having at its ends sprocket wheels 1S, each'wheel 1S lying in the same vertical plane -as the corresponding wheel 16. Again, at the up er frort corner of the frame is a power s iaft 19 having sprocket wheels 20 in the planes of the' afore` said sprocket wheels. The shaft 19 furthermore carries at its ends drive sprocket wheels Specification of Letters Patent. App'ncaaon med March 1s, i908. serial No. 421,339.

21. Operating over each set of sprocket wheels 16, 18, and 20 is a chain belt 22 of any suitable or approved construction,preferably, however, of the detachable link ty c. The 6i) chains 22 therefore operate in parallil planes and are of substantiady the saine length.

In order to rovide a certain amount of adjustment in t e length of the chains 22 any saine may be mountedin adjustable earings. As indicated the shaft 15 is mounted in a bearing 23 whereby the shaft 15 nia be raised or lowered as may be necessitate by usage. This shaft and the parts connected therewith are supposed to be located at or below the surface of the body of Water to be elevated,

Connected to and suspended between the chains 22 is an endless series of buckets 24. 75 These buckets may be connected to the chain by any suitable devices, but preferably they are connected rigidly to elements of the chain whereby they are prevented from liavinr movement inde endent of the movement olf the chains, in ot ier words there is no ivotal or other movement of the buckets wit relation to the lines of the chains. `By this means each bucket has a fixed position with relation to the plane of the two opposite portions of the chains to which the bucket is attached. As a suitable and convenient, as well as a. cheap means, for thus securing the buckets to the chains there are provided` each end of a. bucket. Ea' li link 22 has a usual body portion correspor. ing to the usual chain links whereby the link 22 coperates with the sprocket wheels 16, 1S, and 20 in the same manner as the other links. The inner bar, however, of the link is provided with ears 22" which lie in the same plane and at right angles to the said bar. Preferably s aid ears extend on opposite sides ofthe veitical plane of the link.

Each bucket 24 may be of any construction adapted for the purpose of the invention,' ireferably, however, made of sheet metal and 'rom a single blank in order to increase the strength, durability, and cheapiiess of the saine. As plainly indicated inthe drawings the blank comprises a number of features, and when made up into a bucket the features or elements a, b, and c, at each end of the adding strength at the particular point where needed, the peint of attachment of a link 22'@ one or .more of the vshafts supportinv the 65 special links 22 one of. which is secured to 90 v The ears 22T of a link lie against the outer face of `one of the said elements, indicated as c, and securing means such as rivets pass through all three of said features, securely fastening the link to the bucket and assisting in firmly securing the parts of the bucket together. These parts are furthermore secured by additional means such as bra-zine so as to make the bucket water-tight, the otier portions of the blank indicated by the letters d, e, and constitute a. back, front, and bottoni, respectively, said lastmentioned niembeis being rectangular.

Considering the open portion of the bucket as the top, the tcp or upper edge of the back d always leads and the bucket preferably is secured to the chains' '22 so that the upper edge of the back and the inner edge of the bottom lie in a plane substantially parallel to the plane of the chains. By this arrangement it will be seen that when tlie bucket is supplied with water the bulk of the watei will lie largely below the plane of the connected links, and that t-lie bucket will be almost entirely ,/iilled with wat-e1'. As the bucket is carried upward over the shaft 17 the bucket will tilt gradually, and the contents thereof will be emptied. into a chute S, the projecting lip at the forward edge of the bucket back preventing any premature spilling and 10S of. water. The trough oi chute S will therefore receive the water from the buckets as they pass successively over the shaft 17 and convey it away to any suitable or preferred place of deposit or use, as for instance for irrigation purposes.

Iiiasniucli as the buckets are carried downwardly into the source of water su ply with the open portions downward it ias been found desirable to provide each bucket with one or more automatically operating valves, whereby the air contained in the empty buckets and which would require an uniieeesl sary expenditure of power to force the buckets downward into the water,-inay escape. Asa suitable illustration of such valves there is provided in the bottom of each bucket a hole 25 through which projects loosely a bolt orlunger 26 having on the outside a head 27 ant on the inner end a nut 28. Adjacent to the nut 2S is a washer or gasket 29 which together ith the bolt constitutes a valve. The inner face of the head 27 is provided with a plurality of project-ions 27 which may contact with the bottom of the bucket and )reveiit any posfiihility of the said head .27 c osing the hole 25 when the bucket is inverted, at which time the air must have free exit. As the bucket entexs the water the air contained therein will pass freely out through the hole 25 and between the head 27 and the bottoni of the bucl-v fi.. As the bucket turns about the shaft 15 the position of the valve will automatically chan-ge and by 'the time the bucket is filled with the water the gasket 29 will be seated against the bottom of the bucket, substantially closing the h0le.

The mechanism thus far described may be operated by any suitable power or hand devices, depending upon the capacity of the machine. As a suitable illustration of such power devices there is indicated a transverse sliaftSO jouriialed on suitable brackets preferably within a triangle determined by the chain belts 22. At each end of said shaft 30 is a sprocket wheel 31 connected by a link belt 32 withl the corresponding sprocket wheel 21 of the shaft, 19. r ulley or other power wheel 33 is connecte to the power shaft 34 and by means of a set of gears 35 the shaft 30 is driven from the power shaft 34. In this connection it will be ap )arent that many minor details of constiuction may be varied without departing from the spirit of the inventionor saciiiicing an of its advantages so long as the scope of t ie same 'as de-4 fined by the ap )ended claims is maintained.

Having thus described the invention, what is claimed as new, is:

1. In a device of the character set forth, the combination of an upright tower, shafts journaled at the upper and lower corners of tlie rear of the tower, a shaft journaled at the top of the front of the tower, sets of three sprocket wheels secured to the ends of the sia-fts aforesaid, the sets lying in parallel planes, sprocket chains operating in said planes over said wheels, means for driving said chains, and a series of buckets extending between and secured to said chains, each bucket being provided wit-li an automatic valve comprising a bolt having a head at one end and a nut at the other, the inner face of the head being provided with a plurality of projections adapted to engage the bottom of the bucket when the bucket is inverted.

2. The liereindescribed bucket for endless water conveyers comprising bottoni, rear, front, and end ioitioiis, the to i being open and the bottom lbeing perforated and the perforation being fitted with aii automatic alve consisting of a bolt passing through the perforation and having at one end a head and at the other end a nut, the head being provided on its inner face with a plurality of projections adapted to engage the bottom of the bucket in one position of the latter, and a gasket adjacent to said nut adapted to engage the bi ttoni of the bucket iii another position of the latter to close the perforation.

In testimony whereof I aitix my signature in presence of two witnesses.
